DUMP-CAR.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed November 7, 1906. Serial No. 342.371-

To all whom it may concern:

Be it known that I, O'rro W. MnIssNnn, a citizen of ithe United States,residing'in the city of Montreal, Province of Quebec, Dominion ofCanada, have. in-

' vented certain new and usefulImprovements in Dnmp- Cars, of which thefollowing is a specification.

My invention relates to dump cars, especially to dumpcars of theNational type, comprising a bottomcontaining dumping doors by means ofwhich the load may be discharged at the sides of the car, and the objectof the invention is to provide a simple, efficient and economical meanswhereby the load may be dis charged without interfering with the tracks.To this end my invention consists in the combinations and detailshereinafter set forth and'clainied.

' In the accompanying drawings-Figure 1 is a side elevation of a portionof a dump car having my iniprovements applied thereto. Figs. 2 and 3 aredetail perspective views. Figs. -:l and 5 are end elevations,

partly in section, showing the operation of the dumping doors.

In discharging the load at the sides of the car, it is some timesdesirable to discharge the load at some dis tance from the track, inorder that the material discharged from the car may not fall upon thetrack and prevent the movement of the car upon the track. In thecarrying out of this purpose I provide a car of the National type,which, as is well-known to those skilled in this art, comprises a bottomhaving a series of dumping doors 0 hinged near the center sill ol' thecar. These dumping doors are operated by means of a reciprocating rod 11traveling upon an inclined truck (I secured to the frame portion of thecar and engaging the track 0 upon the door. When closed, the doors,

in combination with-the floor plates, l'o'rm a substantially fiat bottomcar and the doors extend from thc center sill to the sides a of the car.In order to provide means for discharging the load from a car of thistype at. a point remote from the rail, in those cases in which 40 such adischarge is desirable, I provide the doors with extensions 6* hingedalong the outer edge of the doors. The form of hinge which I haveemployed comprises a loop 70 attached to the extension and a hook kengaged by this loop, said hook being attached to the main por tion ofthe door along the front edge thereof. Connect ing the outer edge of thedoor with the side a of the car is a chain e connected at one end to theside of the car by a hook e and at its other end to the extension by aneye-bolt e.

l l l l l l I l l l fl l l l l l l l l It will be observed that when thedumping doors are closed the extension 0'' hangs downward at the outeredge thereof in an inoperative position. The chain :2 is of such lengththat when-the dumping doors are oponed-as shown in Fig. 5the hingedextensions are raised so as to form practically a continuation of thesurface of the dumping doors, thus enabling the material to pass overboth the main portion of the dum ping doors and the extension thereofand be thrown outwardly at some distance from the track.

In order to hold the extension in its inoperative posit ion when thedoors are closed, I provide a chain at an intermediate point with linksIt having ahook momberf, which hook member is adapted to engage with thehook g on the track d. One of the links it is provided with a slidingloop it adapted to slide over the free end of the hook f and hold thehook in the position shown in Fig. 4. By this means the chain e is heldagainst the side of the car, preventing the outward movement of theextension 0 It will be observed that owing tothefact'that the loops onthe extensions engage the open hook k while the chain engages the openhook t the pxtensions may readily be detached from the free ends of thedoor so that wvhon the car is in motion the extensions may be removedtherefrom.

It is thus possible to send the cars from place to place without theextensions. the extensions being applied to the doors upon arrival atthe point of discharge.

'l c operation of my device will be readily understood wiihout furtherdescription.

I claim:

l. A car of the class described having a floor providc l with openings,hinged dumping doors completely llliing the openings when in closedposition, hinged extensions for the doors, said extensions dependingfrom the doors when the doors are closed, and means for bringing theextensions into substantial nlinelnent with the doors when the doors :1re open.

2. A -mof the class described having the usual conr plvtc sides, tloocomprising hinged (lumping doors whose tree edges engage the sides ofthcczu's when the doors are in closed position, and extensions mountedon the tree edges of the doors and forming;- a continuation of the doorswhen the doors are open.

3. A our of the class described having :1 floor provided with dooropenings, hinged (lumping doors filling said openings when closed,ekiension members for said doors, and means l'or dciachnbly mounting theextension memhers on the froeedgos of the doors.
